Hello Joy52now,
Thanks for using Apple Support Communities.
From your post I understand that you deauthorized all of your computers that were associated with your Apple ID, and you would like to now authorize the computers you have. To authorize your computer for your Apple ID purchases, please follow the directions below.
- If you don't have iTunes on the computer you want to authorize, download and install the latest version.
- Open iTunes.
- From the menu bar at the top of your computer screen, choose Store > Authorize This Computer.
If you are using iTunes in full-screen mode, hover your mouse at the top of your computer screen. The menu bar appears. Exit full-screen mode by pressing the Control, Command, and F keys on your keyboard.
If you're using a Windows PC, and you don't see the menu bar, press the Control and B keys on your keyboard or follow these directions to show the menu bar. In earlier versions of iTunes, you can access this option from the Advanced menu.
- Enter your Apple ID and click Authorize.
If iTunes asks you to authorize your computer again, it won't use a new authorization. iTunes uses the same authorization for the same computer.
Authorize your computer in iTunes - Apple Support
Have a great weekend.
